I had the same idea. But I've only run into issues due to the fact that terraform is unable to poll an arbitrary CRD status field and block until a condition is met. Replacing it with the Kubernetes provider would require keeping the wait logic anyway (in null_resource), giving you more moving parts and worse error messages for no real gain.

I have reviewed the prose content within the provided git diff against the official STACKIT branding guidelines and product documentation. The focus was on ensuring that all service names, product terms, and brand identifiers align with the established STACKIT nomenclature.
π Terminology Audit Results
The following observations were made regarding the use of STACKIT terminology:

This aligns with the official product name STACKIT Kubernetes Engine (SKE).stackit_edgecloud_instance,stackit_edgecloud_kubeconfig, andstackit_edgecloud_token.

1. STACKIT Services Identification
Based on the provided git diff, the following STACKIT services and resources are being provisioned or configured:

1. STACKIT IAM or Authorization Misconfigurations
The Terraform provider configuration in
010-provider.tfusesservice_account_key_path = var.stackit_service_account_key_path. While using a path variable is better than hard-coding the JSON content, the security of the entire infrastructure depends on the protection of this file on the machine running Terraform. Ensure this key is managed via a secure secret management system and not stored in plain text on local developer machines or CI runners. Service Accounts2. Missing STACKIT-Specific Security Controls
π΄ High: Overly Permissive Security Group Rules
In
040-network.tf, the security group rules for bothingressandegress(TCP and UDP) are defined without specifying any port ranges or source/destination IP ranges.By default, if no ports or CIDRs are specified in the provider/resource (depending on the specific provider implementation of the STACKIT API), this risks opening all ports. Even if the provider defaults to "all," this violates the Principle of Least Privilege Introduction Security In Networks Security In Networks.

The current design uses a single
stackit_security_groupfor both Control Plane (CP) and Worker nodes.π‘ Medium: Absence of Private Endpoints/Internal Routing
The architecture relies on outbound internet access for STEC registration and image pulls. While necessary for the initial setup, for a production-hardened environment, you should evaluate if these components can communicate via private endpoints or internal STACKIT services to minimize exposure to the public internet Security In Networks Security In Networks.
Proposed Network Topology Improvement:
3. Secrets, Credentials, or Sensitive Values
The PR uses
local_sensitive_fileto write the.stec.kubeconfig.jsonto the local filesystem [030-edge-instance.tf]. While the file permission is set to0600, this file contains highly sensitive credentials..stec.kubeconfig.jsonand the.generated/directory are added to.gitignoreto prevent accidental commits of sensitive cluster access files.4. STACKIT Compliance and Audit-Logging Considerations
The use of Terraform (Infrastructure as Code) is a positive security control as it provides versioning and traceability Security In Networks Security In Networks. However, ensure that the execution of these Terraform plans (especially the
local-execscripts that interact with the STEC API) is performed within a controlled environment where the logs of the actions taken (not just the code changes) are captured and stored for audit purposes.The
stackit_edgecloud_tokenresource generates a token for UI access. Access to the STEC management plane should be audited via STACKIT IAM logs to ensure that only authorized users are interacting with the edge cluster management layer.4. STACKIT Compliance and Audit-Logging Considerations
As a senior architect, I recommend focusing on the visibility of administrative actions and the lifecycle of the credentials being provisioned. While the infrastructure is defined as code, the actual "runtime" actions performed by the scripts and the management plane must be traceable.
π‘ Medium: Auditability of the STEC Management Plane
The PR introduces several resources that interact with the STACKIT Edge Cloud (STEC) management plane, specifically the
stackit_edgecloud_tokenandstackit_edgecloud_kubeconfig.kubeconfigcontains a permanent, secret access token that cannot be revoked Authentication. If this token is used by automated processes (like thelocal-execscripts in050-images.tfand070-edge-cluster.tf), those actions will appear in the STACKIT Audit Log as being performed by the service account or user associated with that token.π‘ Medium: Centralized Log Management for Edge Clusters
The current deployment focuses on the compute and networking layers but does not explicitly provision a centralized logging solution for the workloads running within the Talos Linux nodes.
Logging Strategy Comparison:
Recommended Observability Flow:
The STACKIT Audit Log provides a history of events for the last 90 days via the STACKIT Portal [Audit Log]. If your compliance requirements (e.g., GDPR or industry-specific regulations) require longer retention, you should implement a strategy to export these logs.

Repository Convention Review
The provided git diff has been reviewed against the established repository standards and STACKIT-specific provider requirements. While the example demonstrates a high level of technical sophisticationβparticularly in bridging the gap between IaaS and the STEC Kubernetes API via
local-execβthere are several deviations from the required conventions.β Deviations from Repository Conventions
1. Missing Documentation Files
The example directory
examples/iaas-edge-k8s-cluster/contains aREADME.md, but it is missing the mandatoryMAINTAINERS.mdfile.Fix:
2. Provider Version Constraints
The convention requires all providers in
required_providersblocks to have an explicit version constraint. In010-provider.tf, thestackitprovider uses a pessimistic constraint (>= 0.107.0), which is acceptable for general use but deviates from the strict "explicit version" requirement often used in stable examples to ensure reproducibility. More importantly, thelocalandnullproviders are defined, but theexternalprovider (used in050-images.tf) is missing from therequired_providersblock in010-provider.tf.Fix:
π STACKIT-Specific Observations
Beta Resource Configuration
The implementation correctly identifies that the Edge Cloud resources (managed via the STEC API) are not natively part of the standard STACKIT Terraform provider resource set. The architect has correctly implemented the
enable_beta_resources = trueflag in thestackitprovider block, which is required to interact with experimental or preview features Stackit Terraform Provider.Authentication Pattern
The example uses the Key Flow via
service_account_key_pathDocs. While this is a valid and common method for local development and specific CI/CD pipelines, for production workloads (especially in GitHub Actions or GitLab CI), I recommend transitioning to the Workload Identity Federation (WIF) flow to eliminate the need for long-lived static JSON keys Docs.Architecture Summary
The example uses a "Bridge Pattern" to manage the lifecycle of the Edge Cluster:

π STACKIT Cloud Advisor
1. STACKIT IAM or Authorization Misconfigurations
The use of
local_sensitive_file.stec_kubeconfigto write the STEC kubeconfig to disk (.stec.kubeconfig.json) is a significant risk. While the file permission is set to0600, the content of this file (which contains a permanent, secret access token that cannot be revoked Authentication Authentication) will be stored in plain text within the Terraform state file. If the state is stored in an unencrypted or insufficiently protected backend, the entire STEC management plane is compromised.The provider configuration relies on
var.stackit_service_account_key_path[0.10-provider.tf]. While using a service account is standard, the architect must ensure that the identity associated with this key follows the principle of least privilege and that the key itself is managed via a secure vault rather than being passed as a local file path in a CI/CD environment.2. Missing STACKIT-Specific Security Controls
The
stackit_security_group_ruleresources for bothingressandegress(TCP and UDP) do not specify any IP ranges or port restrictions [040-network.tf].ingressto specific management IPs or internal subnets and restrictegressto only the necessary ports for STEC registration (TCP 443) and image pulls [040-network.tf].The architecture uses a single

The GitHub Actions workflow adds
CLOUDMENT_TOKEN: ${{ secrets.CLOUDMENT_TOKEN }}[0.github/workflows/ai-pr-review.yaml].

Repository Convention Review
The provided git diff has been reviewed against the specified repository conventions and STACKIT-specific provider best practices. While the example is structurally sound and follows most organizational rules, there are several deviations regarding provider versioning and STACKIT-specific resource configurations.
1. Repository Convention Deviations
Deviation: Missing explicit version constraints for all providers
The
010-provider.tffile uses>=constraints for thestackit,local, andnullproviders. While therequired_providersblock is present, the convention requires an explicit version constraint (typically a fixed version or a more restrictive range) to ensure environment reproducibility.2. STACKIT Provider & Usage Concerns
Concern: Beta Resource Opt-in
The example utilizes
stackit_edgecloud_instance,stackit_edgecloud_kubeconfig, andstackit_edgecloud_token. These are part of the Edge Cloud service, which is currently in a beta state. To ensure the provider correctly handles these resources, theenable_beta_resourcesflag must be explicitly set totruein the provider block.Status: Correctly implemented in
010-provider.tf.Concern: Security Group Rule Definition
In
040-network.tf, the security group rules are defined using a block syntax for the protocol:protocol = { name = "tcp" }. While this is functional, ensure this matches the specific provider schema requirements for the version being used.Concern: Server Boot Volume Configuration
In
060-servers.tf, thestackit_serverresource uses aboot_volumeblock withsource_type = "image".stackit_volumemanagement.The current implementation correctly uses the
data.external.image_idsto bridge the gap between the custom Talos image upload and the server creation.Architectural Note on EdgeCloud Integration
The architecture uses a "bridge" pattern to manage the STEC (Stackit Edge Cloud) Kubernetes API, which is not directly managed by the STACKIT Terraform provider.
This is a necessary workaround because the
EdgeClusterandEdgeImageresources are CRDs on the STEC management plane rather than native STACKIT IaaS resources.Summary of Findings

STACKIT Terminology & Product Name Review
As a senior architect, I have reviewed the provided git diff against the official STACKIT branding guidelines and product documentation. The primary goal was to ensure that all prose content, system prompts, and variable descriptions adhere to the correct casing and nomenclature for STACKIT services.
Summary of Findings
The diff shows a significant improvement in brand consistency, particularly in the transition from generic "AI" terminology to specific STACKIT product names. However, there is one specific terminology discrepancy regarding a service name used in the Terraform variable descriptions.

The implementation of the

Users should be aware that beta services may have different support characteristics Faq.disk_size_gbincludes a validation rule ensuring a minimum of 32 GiB. This aligns with STACKIT's technical requirement that Talos Linux requires at least 32 GiB of capacity, though 100 GiB is specifically recommended by STACKIT for optimal operation Faq Faq.required_providersblock correctly implements explicit version constraints (e.g.,version = ">= 0.107.0"), which is a best practice for infrastructure stability.cluster_namevariable documentation correctly notes the requirement for RFC 1034 compliance, which is critical for resource naming in STACKIT.3.

The addition of

Repository Convention Review
The provided git diff has been reviewed against the specified repository conventions and STACKIT provider best practices. While the example is structurally sound and follows most organizational rules, there are a few deviations regarding provider versioning and resource configuration.
1. Repository Convention Deviations
010-,020-, etc.snake_caseand havedescriptionattributes.required_providersblock in010-provider.tfuses inequality constraints (>=) rather than explicit version constraints..tffiles.Fix for provider versioning:
To comply with the requirement for explicit version constraints (pinning), update the
required_providersblock to use exact versions or more restrictive constraints.2. STACKIT Provider & Usage Concerns
A. Beta Resource Opt-in
The example utilizes
stackit_edgecloud_instance,stackit_edgecloud_kubeconfig, andstackit_edgecloud_token. These are part of the Edge Cloud service, which is currently in a beta state. While the provider block correctly setsenable_beta_resources = trueStackit Terraform Provider, it is important to note that beta resources may be subject to breaking changes.B. Security Group Rule Definition
In
040-network.tf, the security group rules are defined using a block syntax for the protocol:protocol = { name = "tcp" }. While this is functional, ensure this matches the specific schema requirements for the provider version being used, as some versions of the STACKIT provider may expect a simple string for the protocol name.C. Server Network Attachment
The example uses a "pre-creation" strategy for NICs (
stackit_network_interface) and then references them in thestackit_serverresource. This is a highly recommended pattern for STACKIT Compute Engine to ensure that security groups and network configurations are fully applied before the VM boots, preventing race conditions during the initial registration of the instance.D. Authentication Best Practice
The example uses the Key Flow via
service_account_key_pathDocs. For production CI/CD pipelines (e.g., GitHub Actions), I recommend transitioning to the Workload Identity Federation (WIF) flow, which is more secure as it eliminates the need for long-lived static JSON keys Docs.β π Example README

Based on my review of the provided pull request commit messages, I have evaluated them against professional standards for traceability and clarity within a STACKIT development environment.
Review Summary
The commit message provided is not vague, but it could be improved to better align with professional documentation standards.
example(edge): basic example on how to deploy edgeDetailed Analysis & Recommendations
While the message
example(edge): basic example on how to deploy edgeprovides enough context to understand the intent, a senior architect looks for messages that facilitate rapid debugging and automated changelog generation. In a professional services repository, we want to know exactly which resource or configuration is being introduced.Suggested Improvements
If you wish to elevate the quality of your commit history to ensure maximum maintainability, consider the following alternatives:
More Descriptive Alternative (Focus on Resource):
docs(edge): add deployment guide for STACKIT Edge resourcesdocs) and identifies the specific STACKIT service/resource being addressed.Action-Oriented Alternative (Focus on Implementation):
feat(edge): implement initial deployment template for edge nodesfeat(feature) is more accurate thanexample.Architect's Pro-Tip for STACKIT Repositories
To maintain a high-quality repository, I recommend adopting a Conventional Commits pattern. This ensures that when you look back at your history via the Blame File View in STACKIT Git, you can immediately distinguish between a bug fix, a new feature, or a documentation update.
Recommended Pattern:
